CELESTIN

What is Sr in human body?
 
Strontium (Sr) is a metal that is closely related to calcium (Ca) in the body, and has beneficial or toxic effects on bone formation. Ninety-nine percent of strontium is stored in the teeth and bones after uptake in the body.What is the biological role of strontium?
 
Strontium is a plant growth stimulant and can replace calcium required by Chlorella [63]. Plants usually contain the same Sr/Ca ratio as their corresponding soil extracts, and this ratio varied in England between 1.4 and 5.7 mg Sr/1000 mg Ca.
What foods contain strontium?
 
What Is Strontium? Strontium is a mineral found in seawater and soil. In your diet, you get it mainly from seafood, but you can also get small amounts of it in whole milk, wheat bran, meat, poultry, and root vegetables. Strontium is similar to calcium.4 Dec 2022
Does the body need strontium?
 
No recommended intake levels have been established for strontium, since it is not considered essential for humans. However, preliminary research in humans suggests that 600–1,700 mg of strontium, taken as a supplement in the form of strontium salts, may increase bone mass in the vertebrae of people with osteoporosis.
Why take strontium at night?
 
Take your strontium before bedtime at night.

It has been suggested that bone resorption is most active at night, so taking strontium citrate just before bed may result in strontium exerting more of its antiresorptive effects when they are needed most. Strontium can be taken with or without food.10 May 2023
Can you take strontium instead of calcium?
 
Many drug treatments for osteoporosis help restore the balance to make your bones stronger. Strontium ranelate is thought to work in a different way. Strontium ranelate replaces some of the calcium found in bone. This may be how it helps to improve bone strength
What are the symptoms of high strontium?
 
* Strontium Chlorate can cause nausea, vomiting, diarrhea and abdominal pain. * High levels can interfere with the ability of the blood to carry oxygen causing headache, dizziness, and a blue color to the skin and lips (methemoglobinemia). Higher levels can cause trouble breathing, collapse and even death.
 
STRONTIAM is a village in Scotland, where for the first time was STRONCIUM found.
Strontium is MINERAL - hell blau with yellow coloured.
 

Strontium’s name comes from Strontian, a village in Scotland. It is said to have first been found in the ores of lead mines in Strontian in 1787. Some years later in 1808, it was was isolated in its metallic form using electrolysis by Sir Humphry Davy at the Royal Institution in London. (17)

In the 19th century, the first large scale use of strontium took place when it was employed to extract the sugar from sugar beets. The next big and interesting use of this alkaline earth metal was when it was used in the television production industry, specifically in the cathode ray tubes of color televisions. (18)

 

Sr is said to be the 15th most abundant element on Earth and it’s common to find it in nature. Both soil and seawater contain this mineral. The Earth’s crust also has Sr at an estimated average of 360 parts per million. (19)

If you’re a fan of red fireworks, you can thank strontium (specifically gaseous strontium monochloride) for that brilliant color you see every 4th of July. It’s also used to create that alerting red color in emergency flares. (20)

Celestin, nebeský kámen

Celestin je chemicky síran strontnatý (SrSO4). Název pochází z latinského "coeli" = nebesa, pro jeho světle až středně modrou barvu. Má sloupcovité, tabulkovité, prizmatické a dobře omezené krystaly.

Krystaly jsou dobře štěpné ve dvou směrech, průsvitné až průhledné. Nejčastěji však celestin tvoří zrnité, zemité, celistvé agregáty a konkrece.

Největší celestinová geoda

Největší celestinovou geodu na světě našli v roce 1897 při hloubení studny ve vinařství Heineman (Heineman Winery). Vinařství se nachází ve státě Ohio (USA) a jeskyně (geoda) je dodnes přístupná. Stěny jeskyně jsou pokryty krystaly celestinu 20 - 45 cm dlouhými a až jeden metr širokými! Původní jeskyně byla však mnohem menší, protože krystaly byly těženy a prodávány k výrobě ohňostrojů (stroncium obarvuje plamen karmínově červeně). Majitele vinařství ale v době prohibice napadlo, že by mohl za poplatek geodu zpřístupnit veřejnosti. Toto řešení nakonec pomohlo vinařství přežít a dodnes nám zachovat jejich víno i tento mineralogický unikát.

Vznik celestinu

Celestin vzniká především v mořských lagunárních jílovitých a slínitých usazeninách, z nichž je těžen jako zdroj stroncia. Může se vysrážet přímo z mořské vody a často se jako vedlejší složka objevuje v evaporitických ložiscích. Méně běžný je vznik hydrotermální. Doprovodnými minerály jsou anhydrit, halit, kalcit, aragonit, sádrovec, síra, galenit, sfalerit.
